How do I locate my Ford F-350 super duty fuse & relay identification?

Answer by  joshuas (90)

There are many ways. The easiest is to go to a Ford dealer and a mechanic will be happy to point it out. Another way is to buy a Hannes book whick breaks down every part of your truck and is great to have for any project you have to perform on your truck.

I would go to Motomanuals. com and look for the appropriate Haynes or Clymer manual for your year and model of truck. Both Haynes and Clymer manuals have good detailed wiring and electrical diagrams as well as the correct fuse block diagrams. If that is no help then you should consult a Ford Dealer and I am sure they could help.

First we have to remove the battery terminals for safety , then open the hood by pulling hood lock, under the hood you will see a box or cover on that says Relay centre the fuse you are looking for might be there.

The fuse and relay ID on an F-350 is located under the gearbox. You'll need to remove the gear panel and then take the casing out.

The best thing to do is go to and they will have an entire section just on your truck and the fuses. You can then find the diagram and print it out that way you will always have it in your truck for when you may ever need it.

These wiring schematics are available online at many websites. You also can go to your local ford dealer and they will happily print out the fuse and relay diagram at no charge as a courtesy to a ford vehicle owner. Otherwise your library will have repair manuals with complete diagrams at no cost.

You should either contact a Ford dealer for a service manual or locate one at a bookstore. This should include all the electrical diagrams showing any fuses and relays.

Start by looking online. A lot of site offer scans of oem diagrams and manual. Most repair manuals include diagrams so look around for of those or a factory manual.
